MOTOR-DRIVING DEVICE OF AN ELECTRIC CAULKING GUN - A motor-driving device of an electric caulking gun has a micro-controller unit (MCU), a direction-changing module, a motor and a speed sensor. The direction-changing module and the speed sensor are electrically connected to the MCU. The direction-changing module is electrically connected to the motor, and the speed sensor detects a speed of the motor. The MCU is built in with a speed determination procedure comparing an actual speed of the motor acquired from the speed sensor with a preset speed. If the actual speed is lower than the preset speed, it indicates that the resistance at a tube nozzle of the electrical caulking gun increases and the direction-changing module increases the speed of the motor to maintain a preset caulk discharge rate. Given the motor-driving device, the operational inconvenience arising from the unstable caulk discharge rate of conventional electric caulking gun can be tackled.

ELECTRICAL CAULKING GUN - An electrical caulking gun has a gun body and a clutching device. The clutching device has a clutching switch, a linking lever, a clutching block and a block spring. The clutching switch is mounted on the gun body and has a pressed segment and a pushing segment having an inclined pushing surface. The linking lever is pivotally mounted in the gun body and has an abutting end and a pushing end. The abutting end abuts with the pushing surface of the clutching switch. The clutching block has an inclined pushed surface and an engaging rod. The engaging rod detachably engages a transmission device of the caulking gun. The block spring provides a force to push the engaging rod on the clutching block to engage the transmission device.

Derailleur Cable Detecting Assembly For An Electric-Auxiliary Bicycle - A derailleur cable detecting assembly for an electric-auxiliary bicycle has a body and a detecting device. The body is mounted on a frame of the electric-auxiliary bicycle, is connected to a derailleur cable and has a casing and a cover. The casing has a chamber and a through hole. The cover is detachably mounted on the casing to mount a cable wire of the derailleur cable in the body. The detecting device is mounted in the body, is connected to the derailleur cable and has a circuit board and a magnetic element. The circuit board is mounted in the chamber of the casing, faces the cable wire and has an electric wire and multiple magnetic sensors. The magnetic sensors are mounted on the circuit board at intervals. The magnetic element is mounted on the cable wire between the casing and the cover, facing the magnetic sensors of the circuit board.
